Book Description
In this work, a new method for site-specific investigation in solid-state DNP called "Specific Cross-Relaxation Enhancement by Active Motions under DNP" (SCREAM-DNP) is presented and used to gain dynamical and structural information in different biomolecular systems. SCREAM-DNP allows to spectrally filter out the background resonances and is used as proof of binding between a ribonucleic acid and a ligand. Moreover, SCREAM-DNP is used for distance determination up to the subnanometer range.eng

Book Description
Paramagnetic NMR is a growing technique that represents an increasingly important tool for the investigation of biomolecules. This book presents an update and overview of the paramagnetic NMR phenomena and effects as well as guidelines for practical implementation of state-of-the-art experiments. All experiments are supported by a solid theoretical foundation. Areas mentioned are the development of solid state NMR, the use of paramagnetic tags providing information on the structure and mobility of the investigated systems, and dynamic nuclear polarization to increase sensitivity. Compiled by experts in the field, this book has international appeal for researchers as well as students interested in magnetic resonance and structural biology who require experimental support and accessible information.

Book Description
Solid-state NMR has recently emerged as a key technique in modern structural biology, by providing information at atomic level for the characterization of a wide range of systems that cannot be investigated by other atomic-scale methods. There are now well established protocols for sample preparation, resonance assignment and collection of structural restraints, that have paved the way to the first three-dimensional structure determinations at atomic resolution of biomolecules in the solid state, from microcrystalline samples to fibrils and membrane-associated systems. These determinations are however still far from being routine, and larger breakthroughs are expected with further methodological and hardware developments. Accordingly, most of the work presented in this thesis consists of the development of new, sophisticated NMR experiments to improve the sensitivity and resolution of the currently existing schemes for resonance assignment and to extend the capabilities of solid-state NMR in terms of structural investigation of proteins for the analysis of large substrates. These developments notably rely on the use of very high magnetic fields and ultra-fast magic-angle spinning (MAS). We show the great potential of this particular regime, which enables the use of low-power experiments and the acquisition of selective cross-polarization transfers, through-bond correlations and 1H-detected correlations.In particular, we show that homonuclear correlation experiments based on through-bond transfers become competitive alternatives to dipolar transfer schemes. Two new pulse sequences that detect sensitive and resolved 13C-13C through-bond correlations are introduced, which coupled to 15N-13C dipolar transfer steps provide sensitive routes for protein backbone resonance assignment.Furthermore, we demonstrate that narrow 1H NMR line widths can be obtained for fully protonated proteins in the solid state under ultra-fast MAS, even without perdeuteration. In this context, we have developed new strategies for extensive, robust and expeditious assignments of the 1H, 15N, 13CO, 13CA and 13CB resonances of proteins in different aggregation states, and new schemes for the measurements of site-specific 1H-1H distance restraints. This approach relying on the very high sensitivity of 1H spins remarkably accelerates the processes of assignment and structure determination of proteins in the solid state, as shown by the assignment and de novo structure determination of native beta-2-microglobulin. Finally, we apply this new approach to perform resonance assignment and to study structural and dynamic features of three complex protein aggregates: amyloid fibrils formed by native and D76N beta-2-microglobulin, Acinetobacter phage 205 nucleocapsids and measles virus (MeV) nucleocapsids. We also used Dynamic Nuclear Polarization to obtain the first information about RNA in MeV nucleocapsids.We believe that the results presented in this thesis represent a substantial step forward for solid-state NMR in structural biology. With all the current advances in the field, the impact of biomolecular solid-state NMR is likely to increase in the next years.

Book Description
This is the first book in the series to focus on dynamic hyperpolarized nuclear magnetic resonance, a burgeoning topic in biophysics. The volume follows the format and style of the Handbook of Modern Biophysics series and expands on topics already discussed in previous volumes. It builds a theoretical and experimental framework for students and researchers who wish to investigate the biophysics and biomedical application of dynamic hyperpolarized NMR. All contributors are internationally recognized experts, lead the dynamic hyperpolarized NMR field, and have first-hand knowledge of the chapter material. The book covers the following topics: Hyperpolarization by dissolution Dynamic Nuclear Polarization Design considerations for implementing a hyperpolarizer Chemical Shift Imaging with Dynamic Hyperpolarized NMR Signal Sampling Strategies in Dynamic Hyperpolarized NMR Kinetic Modeling of Enzymatic Reactions in Analyzing Hyperpolarized NMR Data Using Hyperpolarized NMR to Understand Biochemistry from Cells to Humans Innovating Metabolic Biomarkers for Hyperpolarized NMR New Insights into Metabolic Regulation from Hyperpolarized 13C MRS/MRI Studies Novel Views on Heart Function from Dynamic Hyperpolarized NMR Insights on Lactate Metabolism in Skeletal Muscle based on 13C Dynamic Nuclear Polarization Studies About the Editors Dirk Mayer is Professor of Diagnostic Radiology and Nuclear Medicine at the University of Maryland and is the Director of Metabolic Imaging. He is a recognized expert on dynamic nuclear polarization (DNP) MRI-based imaging techniques and has optimized acquisition and reconstruction techniques, has constructed kinetic modeling for quantitative analysis, and has developing new probes. Thomas Jue is Professor of Biochemistry and Molecular Medicine at the University of California Davis. He is an internationally recognized expert in developing and applying magnetic resonance techniques to study animal as well as human physiology in vivo. He served as a Chair of the Biophysics Graduate Group Program at UC Davis, where he started to redesign a graduate curriculum that balances physical science/mathematics formalism and biomedical perspective in order to promote interest at the interface of physical science, engineering, mathematics, biology, and medicine. The Handbook of Modern Biophysics represents an aspect of that effort.

Book Description
In this study, a revolution in solid-state nuclear magnetic resonance (SSNMR) spectroscopy is taking place, attributable to the rapid development of high-field dynamic nuclear polarization (DNP), a technique yielding sensitivity improvements of 2-3 orders of magnitude. This higher sensitivity in SSNMR has already impacted materials research, and the implications of new methods on catalytic sciences are expected to be profound.
